Abstract

L'invention utilise le déplacement continu régulier d'une courroie de masquage afin de concentrer les matériaux absorbants entraînés par l'air sur la surface d'un substrat fibreux en déplacement. L'air circulant à travers les zones ouvertes de la courroie de masquage fait pénétrer le matériau entraîné dans la bande fibreuse. Celle-ci sert de filtre afin de séparer le matériau entraîné du flux d'air. Pratiquement la totalité du matériau entraîné est retenue dans la bande fibreuse, ce qui permet d'éliminer les systèmes de recyclage coûteux et complexes de matériau absorbant.
